Thus, the methodology adapted in the present work is a useful starting point for the modeling and designing large scale multiple frequency reactors.
However, the moderate cavitation intensities in dual frequency reactors would favour the physical processes such as extraction and leaching [ 103].
This paper deals with the characterization of an atomic hydrogen source created in a radio-frequency reactor with a helicon configuration.
Reduction of electrostatic charge accumulation in fluidized bed polymerization reactors can reduce the frequency of reactor wall sheeting incidents and decrease the cost of operating fluidized bed polymerization reactors.
The work presented here is focused on the investigation of fullerenes synthesis, using a radio frequency plasma reactor.
Two different ultrasound systems i.e. ultrasonic bath (37 kHz) and a hexagonal triple frequency ultrasonic reactor (28, 40 and 70 kHz) of 15 L have been used.
The γ coefficient is measured in a pulsed radio frequency plasma reactor (13.56 MHz) in non-equilibrium conditions using an actinometric method.
Similarly for the triple frequency ultrasound reactor, coupling all the three frequencies resulted into a final COD of 41,300 mg/L compared to any other individual or combination of two frequencies.
Primary parameters are defined and considered, namely; pressure amplitude, frequency and reactor design; including transducer type, signal type, vessel-transducer ratio, liquid flow, liquid height, liquid temperature and the presence of a reflective plate.
Modelling of a dual frequency ultrasonic reactor has been carried out to understand the effect of introducing a second wave on the cavity dynamics as compared to a single sound wave.
Coincidence of the compression half cycles of the two acoustic waves while using dual frequency sonochemical reactor has a favourable effect on the production of radicals, as it intensifies the transient collapse of the cavitation bubbles [ 102].
